sub-species defined in 1951 yearsub-species - sub-species;
sub-species - Subdivision of a species forming a group whose members resemble each other in certain characteristics, and differ from other members of the species, though there may be no sharp dividing line. Polymorphism is excluded. While breeding is possible and in many cases occurs between members of different sub-species of the same species, it does not occur as freely as within the confines of the sub-species. Because reproductive isolation is incomplete, sub-species nearly always grade into each other. The partial reproductive isolation is commonly due to the occupation of different geographical areas. Some sub-species are probably new species in the making. See also: Binomial Classification.
